I want to share you about this maybe it can help you who confuse with HoN item but Master in DotA item... 
After i search some, there is some way to add DotA item name, under HoN item name when it played.
I found some file, but it first not match with our HoN LAN 1.2.6. The file name is "entities_en.str".
after compare and work with crimson editor (actualy notepad can do it), i can make the file that can make DotA item name, under HoN item name. Run test with my 3 friends, its work. ^_^

how to use : - Extract the file
- Copy to : "your HoN folder" > Game > Stringtables (it will be an overwrite)
Actualy its simple editing, u can learn the entities_en.str and edit what you want, even the Hero Name.
